A dynamic finite element surface model for segmentation and tracking in multidimensional medical images with application to cardiac 4D image analysis.
TLDR
A physics-based approach to anatomical surface segmentation, reconstruction, and tracking in multidimensional medical images using a dynamic "balloon" model--a spherical thin-plate under tension surface spline which deforms elastically to fit the image data.About:

Snakes, shapes, and gradient vector flow
Chenyang Xu,Jerry L. Prince +1 more
TL;DR: This paper presents a new external force for active contours, which is computed as a diffusion of the gradient vectors of a gray-level or binary edge map derived from the image, and has a large capture range and is able to move snakes into boundary concavities.
Journal ArticleDOI
Deformable models in medical image analysis: a survey
TL;DR: The rapidly expanding body of work on the development and application of deformable models to problems of fundamental importance in medical image analysis, including segmentation, shape representation, matching and motion tracking is reviewed.
Journal ArticleDOI
Lane detection and tracking using B-Snake
TL;DR: A robust algorithm, called CHEVP, is presented for providing a good initial position for the B-Snake model, and a minimum error method by Minimum Mean Square Error (MMSE) is proposed to determine the control points of the B -Snake model by the overall image forces on two sides of lane.

Generalized gradient vector flow external forces for active contours
Chenyang Xu,Jerry L. Prince +1 more
TL;DR: This paper generalizes the GVF formulation to include two spatially varying weighting functions, which improves active contour convergence to long, thin boundary indentations, while maintaining other desirable properties of GVf, such as an extended capture range.

4D Spatio-Temporal ConvNets: Minkowski Convolutional Neural Networks
TL;DR: In this paper, a generalized sparse convolutional neural network (GS-CNN) was proposed for spatio-temporal perception of 3D-videos, which can directly process 3D videos using high-dimensional convolutions.

Marching cubes: A high resolution 3D surface construction algorithm
TL;DR: In this paper, a divide-and-conquer approach is used to generate inter-slice connectivity, and then a case table is created to define triangle topology using linear interpolation.

Differential geometry of curves and surfaces
TL;DR: This paper presents a meta-geometry of Surfaces: Isometrics Conformal Maps, which describes how the model derived from the Gauss Map changed over time to reflect the role of curvature in the model construction.
Journal ArticleDOI
On active contour models and balloons
TL;DR: A model of deformation which solves some of the problems encountered with the original method of energy-minimizing curves and makes the curve behave like a balloon which is inflated by an additional force.
Journal ArticleDOI
Volume rendering
TL;DR: A technique for rendering images of volumes containing mixtures of materials is presented, which allows both the interior of a material and the boundary between materials to be colored.

Constraints on deformable models: recovering 3D shape and nongrid motion
TL;DR: This work describes an extrinsic force that applies constraints derived from profiles of monocularly viewed objects and generalizes this constraint force to incorporate profile information from multiple views and use it to exploit binocular image data.
